Techniques for previewing and presenting content of different applications in a user interface are described. In an example, a computer system determines a presentation template defined for a page application. The page application is configured to present a page about a target application, and the page includes a preview area and a body area. The system receives a user selection of an icon in a menu, whereby the icon corresponds to the target application. The system then presents in the user interface contents based on data stored in local memory, whereby the contents are presented according to an arrangement specified by the presentation template for the preview area. The system then receives a user request for additional information about the target application, and subsequently presents at least a portion of the body area of the page based on an execution of the page application.

A system for providing help includes a smartphone having a cellular transceiver and a global positioning subsystem. A call center server computer system has a plurality of agent computers. Software running on the smartphone is configured to recognize a preprogrammed specific utterance and to connect with the call center server computer system. After the preprogrammed specific utterance is detected, the software running on the smartphone initiates a call to the call center server computer system. When the call center server computer system receives the call, the call center server computer system retrieves a data record associated with the smartphone using a caller-id of the call and the call center server computer system assigns an agent computer. At least part of the data record is displayed on a display of that agent computer and an audio connection is made between that agent computer and the smartphone.

A method for providing help includes providing a plurality of data records, each data record having medical information regarding a user and one or more contacts associated with the user. After receiving a call for help at a call center computer system, determining the user based upon an identifier of the call for help and assigning an agent computer of the call center computer system to the call for help then transferring at least part of the data record to the agent computer. The data record of the user is then accessed at the agent computer and after determining a nature of the need for the help, a second call is made to one contact from the data record of the user after selecting the one contact selected based upon the need for help.

A method in a proxy call session control function, P-CSCF, of handling an unauthenticated emergency call originating from a roaming user equipment, UE, which is not attached to the P-CSCF. The P-CSCF receives a SIP INVITE request from the UE, the INVITE request relating to the unauthenticated emergency call, and determines an IP address of the UE. The P-CSCF sends an identity query to a policy and charging rules function, PCRF, indicating the IP address of the UE and requesting other identifiers of the UE, and receives one or more other identifiers of the UE from the PCRF. The P-CSCF constructs a TEL and/or SIP uniform resource identifier, URI, for the UE on the basis of at least one of said other identifiers, inserts the URI into the SIP INVITE request, and sends the SIP INVITE request to a public safety answering point, PSAP. Also provided are corresponding methods in other nodes and for authenticated emergency calls, and apparatus for implementing the methods.

There is a growing problem in correctional facility telecommunications systems in which parties on a voice call may connect inmate callers with restricted parties. Prison communication systems monitor calls to prevent such activity, but in Voice over Internet Protocol (VoIP) environments such systems may fail to detect this activity. The present disclosure provides details of a system and method for using SIP messages common in VoIP environments to detect illicit activity initiated by a party on a voice call within a controlled environment. Scenarios are detected in which a called party connects an inmate caller to a restricted party via three-way call conferencing, call forwarding, or other call features. Corrective actions are then taken when such activity is detected, such as call blocking or alerting officials illicit activity is occurring.

In an attempt to establish a communication session between a first communication entity and a second communication entity, a first message is received. For example, the first message may be a SIP INVITE message. A determination is made, based on a registration message from the first communication entity and/or the second communication entity, that at least one of the first communication entity or the second communication entity is Internet Protocol (IP) version intolerant. In response to determining that the at least one of the first communication entity or the second communication entity is IP version intolerant, one or more IP addresses are adapted in messages (e.g., the SIP INVITE message) for establishing the communication session. The adaption changes/removes the one or more IP addresses to a different IP version to ensure proper IP compatibility.

Methods for operating a device and for managing bootstrapping of devices are disclosed. The method (100) for operating a device comprises computing (102) a derivative of a secret shared between the device and a server entity of a network, generating (104) a temporary bootstrap URI by combining at least a part of the computed derivative with a static bootstrap URI for the network, and sending (106) a bootstrap request to the temporary bootstrap URI. The method for managing bootstrapping of devices comprises generating temporary bootstrap URIs corresponding to devices operable to connect to a network, and updating a network DNS registry to map the generated temporary bootstrap URIs to the IP address of at least one of a bootstrap server instance reachable via the network and/or a bootstrap load balancer. Also disclosed are a device, a bootstrap load balancer, a bootstrap server, and a computer program.

The present disclosure provides a method (500) in a Network Function (NF) node for subscription to notification of data change in a Unified Data Management (UDM) node. The method (500) includes: transmitting (510) to the UDM node a request for retrieval of a user subscription data or a request for registration with the UDM node, the request for retrieval or the request for registration including a callback Uniform Resource Identifier (URI) for use by the UDM node to notify the NF node of the data change; and receiving (520) from the UDM node a response to the request for retrieval or the request for registration.

Devices, systems, and methods are described herein that comprise a multi-screen application which allows users to establish communication sessions with other users of the multi-screen application as well as allowing the user to request multimedia content using the same multi-screen application interface. The user makes a connection request to establish a multimedia session by entering a name or phone number. The multi-screen application uses a request string from the connection request to search a user's contact directory in order to determine possible user connection identifiers associated with the request string. The multi-screen application may additionally or alternatively transmit the request string to a directory server maintained by a service provider. The directory server may provide an endpoint for retrieving multimedia content associated with the string. The multi-media application may be used to allow a user to ‘call’ multimedia content using the same user interface used for calling another user.
